16y^2-12=0

Solution for 16y^2-12=0 equation:

16y^2-12=0

a = 16; b = 0; c = -12;
Δ = b2-4ac
Δ = 02-4·16·(-12)
Δ = 768
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{768}=\sqrt{256*3}=\sqrt{256}*\sqrt{3}=16\sqrt{3}$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-16\sqrt{3}}{2*16}=\frac{0-16\sqrt{3}}{32}
=-\frac{16\sqrt{3}}{32}
=-\frac{\sqrt{3}}{2}
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+16\sqrt{3}}{2*16}=\frac{0+16\sqrt{3}}{32}
=\frac{16\sqrt{3}}{32}
=\frac{\sqrt{3}}{2}
